Cavalcade (1960s)

[Music] this Twisted tornado rack pile of Steel was a microwave radio relay Tower a vital Link in our nation's complex telephone Network minutes after the tower was felled by a tornado surface was restored by switching calls to alternate roots of the network but a temporary Tower must be erected and quickly the chances of a microwave tower being knocked out are very slim however to assure the fastest restoration of any of its 2500 Towers the Bell System conducts emergency full-scale Tower replacement exercises Kurt this is an exercise this is an exercise you have lost the Holden Tower a new tower rolls to its emergency destination at the site bearings are taken to determine the replacement tow position as the prepackaged equipment arrives anchor holes for the tower supports are dug the arrival time is early morning before afternoon has passed the crew expects to have 125t temporary Tower up and operating [Music] la [Music] the new microwave link will receive signals from adjacent Towers some 30 m away technicians pinpoint the incoming signal take it to the left left left a little more left easy whoa he right on frequency Communications are restored television programs telephone calls and data are going through this one was for practice the next one might not be for Crews like this the big task is keeping the nation's Communications [Music] flowing man since he could stand has looked up and the universe has fascinated stargazers from Galileo to Gemini to Garden astronomers today's Amer stargazers spend over $5 million annually to Peak into the [Music] heavens how do you begin the first step is to consult a qualified person for help and choosing the right kind of equipment there's something special for everything from bird watching the satellite [Music] spotting these prism binoculars for example are excellent for wildlife watching but also have the 10 to 20 power magnification necessary to explore distant forms and [Music] shapes a good telescope for beginners is this refractor model which really brings Mars close it has that effect on Fathers and Sons as well as the hobest interest grows he may graduate to this equatorial telescope which allows him to photograph the stars and planets through its lens through giant instruments like the one on M palamar the shifting rings of Saturn remain a quest of science the mountains and Craters of the Moon are of increasing before long a man's spacecraft from Earth will sat down on the Sandy surface and a new era in man's achievements will be born why the upsurge of interest in the heavens could it be that someone's up there looking [Music] back behind the wheel of the car we're driving we're in a world of ergonomics how we react to Tactical design is the stud of ergonomics and it's part of driving an automobile safer than ever before a growing nucleus of autom Manufacturers feels that the safety of a Motorcar is deeply rooted in its basic engineering design one such manufacturer is the British firm that produces the Rover 2000 you won't find the safety engineer here because the company regards all its Engineers as safety engineers and their car is cited by experts as one of the safest anywhere the underlying philosophy is that a safe car is a well-engineered car with Concepts that begin on the drawing boards a car is made up of many systems and how well it operates depends on how well these systems work together hours of testing are required and many prototypes are developed before the final model reaches the production line de Dion rear suspension radio pli tires and disc brakes provide a First Rate combination of handling road holding and stopping all are highly important Innovations in the industry but when they're together in one automobile as in this Rover the driver really has something going for him the driver's ability to handle his vehicle has brought about research in ergonomics some results include orthopedically designed seats strip type speedometers for Rapid reading controls that can be operated without error without looking for the driver's Comfort face level fresh air Ducks there are no shortcuts to safer automobiles indeed experience has shown the true safety features are designed in long before the Prototype rolls out the Earth's resources provide man the substance with which he refines his world it takes about two tons of ore to make a single Pig of lead a curious Paradox this pig of lead while one of our most heavy metals it is also one of the softest which makes it one of the easiest to process to melt cast roll extrude or dropped to form shot lead has a remarkable range of uses often in the most unlikely situations a vital Aid in the transmission of electric power lead is also a prime ingredient in portable electric power storage [Music] [Applause] batteries power from lead acid batteries moves this delivery truck and turns this hand tool yet lead can work against the flow of elect electricity when added to Glass it becomes an insulator of high density and high electrical resistance this is why most light bulb bases in neon tubing are made from lead glass the very idea of lead in glass seems contradictory nonetheless this Goblet of lead crystal was made in England by George Ravenscroft back in the year 1675 lead glass today protects against penetrating X-rays and Lead containers Shield against radioisotopes and other fishable materials philarmonic Hall in New York's Lincoln Center rests on lead pads that dull the vibrations from subway trains this dullness carries through to its gray color yet lead compounds appear in every brilliant Hue widely used in decorating they contribute to our sense of Aesthetics wherever man's achievements they reveal special properties that are the par Parx of lead in this picturesque Countryside farming is a leading occupation but this Farm is strictly for the birds nearly 25,000 ostriches are kept in this unusual farming region in South Africa's Cape Province although Nature has given the ostrich wings that are not suitable for flying it's in these inadequate appendages that the farmer invests ostrich feathers are highly prized in the milliner and garment industry a fully grown bird carries feathers worth up to $20 and they're clipped every 9 months specially selected birds are chosen for breeding the eggs hatch out in about 6 weeks ostrich chicks are very delicate up to the age of 3 months but they grow fast and yield qualtity feathers at 6 months recently this farming region at oorn was the site of the first ostrich race meeting ever to be held in South Africa in true racing tradition the birds display their colors like all good athletes they limber up prior to the competition as the race draws near tension builds in the padic enter the jockeys and their first of many formidable assignments this day to locate their Mount and mount if [Music] possible at last the winged thorough breads are at the gate they're off a clean break for what looks to be a fast field Church Downs was never like this down the straightaway at 30 mph as excitement builds with each skillful maneuver into the home stretch and flying the orange and white it's Lambo alley what else from an ostrich named lumbago
